產(chǎn)品詳情

  • 產(chǎn)品描述：
    人磷脂酰肌醇聚糖4(GPC4)酶聯(lián)免疫試劑盒（CSB-EL009706HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、細胞裂解物樣本中的GPC4含量。GPC4，全稱Glypican 4，是一種位于Xq26.2染色體上的基因，其編碼的蛋白質(zhì)屬于細胞表面硫酸乙酰肝素蛋白聚糖家族。該基因在細胞分裂和生長調(diào)節(jié)中發(fā)揮作用，可能與Simpson-Golabi-Behmel綜合征有關。研究機制方面，GPC4基因的表達與多種生物學過程相關，包括細胞信號傳導、細胞增殖和腫瘤發(fā)生等。試劑盒檢測范圍為0.625 ng/mL-40 ng/mL，適用于基礎科研領域中對GPC4蛋白的功能機制研究，例如腫瘤微環(huán)境分析、干細胞特性探索、胚胎發(fā)育相關信號通路研究等場景，為體外實驗提供穩(wěn)定可靠的檢測方案。本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

靶點詳情

  • 功能：
    Cell surface proteoglycan that bears heparan sulfate. May be involved in the development of kidney tubules and of the central nervous system.
  • 基因功能參考文獻：
    1. The T allele of GPC4 may represent a risk factor for Epstein-Barr virus-associated gastric carcinoma. PMID: 27071854
    2. According to behavioral studies, downregulation of Gpc4 by Gpc4 siRNA decreased spontaneous seizure frequency, while upregulation of Gpc4 by recombinant Gpc4 overexpression led to a converse result. These findings support the hypothesis that increased expression of Gpc4 in the brain is associated with epileptic seizures. PMID: 27425250
    3. serum level elevated in polycystic ovary syndrome and correlated with fat distribution and cardiovascular risk PMID: 26486309
    4. Data suggest gender difference in circulating GPC4 levels in nonalcoholic fatty liver disease; GPC4 levels in women appear to correlate with cardiometabolic risk factors (adiposity/body fat distribution, insulin resistance, and arterial stiffness). PMID: 23633195
    5. new function of miR-125a by targeting gene glypican-4 in cell growth process PMID: 22644326
    6. Findings establish that Gpc4 acts at the interface of extrinsic and intrinsic signal regulation to fine tune stem cell fate. PMID: 22761013
